Abstract: A metal artifact reduction (MAR) method and system for reducing metal artifacts from X-ray images. The method is suitable for CT images generated with metallic elements exterior to a patient being scanned, for example, where external probes are applied to a patient, such as ultrasound probes. The method may be embodied in a computer algorithm for use, for example, in radiotherapy treatment planning and patient positioning procedures. In one application, the disclosed technique improves the dose delivery accuracy in ultrasound-guided cardiac radioablation, making this treatment modality a viable option for cardiac arrhythmias.
